BY MESNE ASSIGNMENTS, TO ELECTRIC- PENNSYLVANIA, A CORPORATIONCONTROLLER-BE GULATOR.

' nolfe'znsen pecially to means for regulating the operation of thesame.

here an electric motor controller is'employed to control an electricmotor which propels an electric vehicle, or which operates in otherrelations where it starts under load, the operator may-move theoperating handle or member of the controllerat such a rate in startingthe motor that, unless the rate of movement of the handle of thecontroller be regulated, a large current will be admitted to the motorbefore the speed thereof has accelerated, thereby wasting considerableenergy and subjecting the motor to an excessive current.

The present invention has for-the object thereof to provide a regulatorfor an electric motor controller which will prevent the operator frommoving the operating member or handle of the controller too rapidly instarting the motor.

In accordance with the present invention in the preferred form thereof,the operating member of the controller has associated therewith a seriesof stops arranged in successioh and a pawl adapted to engage said stops.At each position of the operating member in starting the motor, the pawlengages a stop and prevents said memherfrom being moved to the nextpostition until it is released by manually actuating a releasingmechanism.

An embodiment of'the present invention has been illustrated in theaccompanying drawings, in which Figure 1 is a plan view of a controllerregu lator constructed in accordance with the )resent invention, partsof the regulator eing broken away; and, Fig. 2 is a sectional view onthe line 22 of Fig. 1.

The controller shaft 1 has attached thefeto an operating handle v2 andsurrounding the same is a supporting ring 3, which maybe following is afull, clear, concise,

stationary position upon the This ring supports 'a. plurality of stopsor pins 4, which are arranged in succession. These pins extend throughholes in said ring and have the lower ends thereof extending belowsaidring. The upper ends of said pins are provided .with rest in.depressions around the mounted in a holes.

Upon the controller shaft is mounted a plateor disk 5, which extendsover the supporting ring and has a flange extending This plate has ahole 6 therein covered by a plate 7 and adapted to permit the pins to beraised. The plate 5 supports a pawl or stop block 8, whichpreferablylliasan inclined or beveled rear surface constituting a cam 9,this pawl bemg provided with a projection 10 arran ed between lugs 11,depending from the ottom of the plate. the stop pins when the operatinghandle is moved from the initial position t iereof, and engages a pin ateach position of the operating handle to arrest the movement of thehandle.

A releasing lever 18 is pivoted to lugs 14 depending from the plate 5and has'the forward end thereof situated in front of the pawl or stopblock and adapted to ass beneath the lower ends of the pins. he. rearend of the releasing lever has a plunger 15 resting thereon. The upperend of this plunger extends through the plate or disk 5 and engages atrigger 16 pivoted upon the operating handle of the controller.

When the operating handle is moved forward from the initial ositionthereof to start the motor, the paw comes into enga e-- ment with thefirst in 4 when it reaches t e first position thereof: of the handle isarrested. The trigger may then-be actuated to operate the releasinglever and. thereby elevate the pin in engagement with the pawl to permitthe operating handle to be turned until it reaches the next position Thepawl is arranged to engage and thus the movement at each positionthereof, and prevent the operating handle from being moved from oneposition to the next until the trigger has been actuated to release thehandle. In reversing the handle to stop the motor, it will be noted thatthe beveled rear surface 9 of the stop block will engage beneath thepins movein'entof, the controller handle. arrangement thecontroller-has: an ru ted movement inthe reverse direction.

t is manifest that the present invention is raising the same as the pawlpassesbeneath the, pins, whereby-they WlllDOl; interrupt the By this Isilsceptible of being embodied 1 various been forms, and, therefore, "it.will be understoodtliat-the embodiment of theinv'ention whichillustrated herein may be modified mvarlous ways.
